Anyone running high RPM's yet (VTECH?)
Is anyone running their Sparks in the 8600-8800+ RPM range yet with a remap etc? (Not turbo)
If so what speeds are you getting and are aftermarket valve retainers/shims required?

Can get mine over 8100. Testing a few different props. Still nothing over 8100

Run mine to 8500-8600 with stock repitched prop seeing 54mph with FA removed 402 tune ..

I was going to do the grate and prop but haven't seen much of a gain from others... But repitch will help ...
Try lift the hook out of the ride plate to gain more top speed...

You need velocity stack for na performance at high rpm.

That WORX ride plate would make a difference in handling ...

Looks like WORX has all the pimp bits ... Lol

Theres a lot of talk about people getting these Sparks to 58mph + but no actual proof nor details of how they did it.
